Question

56 +xy-37 *43

Answer 1

Take the slope you're given in the first equation (-1x) and the point you're also given (4,1) and plug it into y=mx=b. So you should have:
\[1=-1(4)+b \]
\[1=-4+b\]
add 4 to both sides, giving you b=5
now that you have a new y-intercept , take the slope you were given in the first place and write an equation. So, y=-x+5, but to know your answer it has to be in standard form (Ax+By=C)
so add x to both sides to give you:
\[x+y=5 \]
that's your answer
